BACKGROUND
This study presents the one-year outcomes of a modified technique for transscleral suture fixation of a posterior chamber intraocular lens (PCIOL) in aphakic eyes.
METHODS
A retrospective chart review was conducted on 45 patients who underwent transscleral suture fixation of a foldable one-piece PCIOL through scleral pockets. Preoperative data and follow-up data for a minimum of 12 months were collected for all patients.
RESULTS
The mean preoperative and postoperative uncorrected distance visual acuity (UDVA) in LogMAR was 2.49 ± 0.54 and 0.54 ± 0.25, respectively ( < 0.01). The mean preoperative and postoperative best-corrected visual acuity (BCVA) in LogMAR was 0.52 ± 0.22 and 0.45 ± 0.24, respectively ( < 0.01). The mean endothelial cell loss was 110.46 ± 11.5 cells/mm. Postoperative complications included transient corneal edema (17.7%), transient elevated intraocular pressure (22.2%), and non-significant vitreous hemorrhage (11.1%). No severe complications were observed.
CONCLUSION
The modified technique provides stable PCIOL placement in aphakic eyes with long-term follow-up.
背景
本研究展示了一种改良技术用于无晶状体眼后房型人工晶状体（PCIOL）经巩膜缝线固定的一年期结果。
方法
对45例通过巩膜袋进行可折叠一体式PCIOL经巩膜缝线固定术的患者进行回顾性病历审查。收集所有患者的术前数据和至少12个月的随访数据。
结果
LogMAR视力表测量的术前和术后平均未矫正远视力（UDVA）分别为2.49±0.54和0.54±0.25（<0.01）。LogMAR视力表测量的术前和术后平均最佳矫正视力（BCVA）分别为0.52±0.22和0.45±0.24（<0.01）。平均内皮细胞损失为110.46±11.5个细胞/mm²。术后并发症包括短暂性角膜水肿（17.7%）、短暂性眼压升高（22.2%）和非显著性玻璃体出血（11.1%）。未观察到严重并发症。
结论
该改良技术在长期随访中为无晶状体眼提供了稳定的PCIOL植入。
